in class, we asked to use a potentiometer and/or photocell to collect serial data from the LED values.


next assignment: LED Meter with shift resistors

I will be using this analog data as output data to a SIPO 74HC164 shift resistor, controlling 8 LEDS. The final step is to great a bar graph, measuring high to low values, 0 being all LEDs are off and 8 being all LEDS are on.



analog data from photocell : range (235 – 770), using 2.2k ohm resistor
